AN ANALYSIS OF THE INFLUENCE OF THE TEXTILE MATERIAL DOUBLING PROCESS BY THERMOFUSING ON VAPOR PERMEABILITY

To confer shape and volume parameters, to ensure dimensional stability of surfaces and contours, some parts of clothing are doubled using the process of thermofusion with certain woven or nonwoven chemicalized materials. A priority in the work of producers of fabrics and textiles is to ensure comfort parameters and functions of apparel products are met and respected. Clothing products should ensure optimum insulation, air permeability, moisture absorption and transfer in order to give the wearer wellbeing and safety. In this paper we propose to analyze the influence of the technological process of doubling on the vapour permeability of the doubled assembly, compared with the permeability of the non-doubled material. As materials made of natural fibers are increasingly required, we focused on two natural fiber fabrics – 100% linen and 100% cotton - and a mixed natural fiber material – 64% linen, 34% viscose and 2% elastane. They were each doubled using thermofusion with woven or nonwoven chemicalized materials composed of wool mixed with polyamide. Laboratory measurements allow us to conclude to what extent the vapor permeability of the thermofused assemblies is influenced

SPIDER SILK

The strengthness and toughness of spider fiber and its multifunctional nature is only surpassed in some cases by synthetic high performance fibers. In the world of natural fibers, spider silk has been long time recognized as a wonder fiber for its unique combination of high strength and rupture elongation. Scientists in civil military engineering reveal that the power of biological material (spider silk) lies in the geometric configuration of structural protein, and the small cluster of week hydrogen bonds that works together to resist force and dissipate energy. Each spider and each type of silk has a set of mechanical properties optimized for their biological function. Most silks, in particular deagline silk, have exceptional mechanical properties. They exhibit a unique combination of high tensile strength and extensibility (ductility). This enables a silk fiber to absorb a lot of energy before breaking (toughness, the area under a stress- strain curve). A frequent mistake made in the mainstream media is to confuse strength and toughness when comparing silk to other materials. As shown below in detail, weight for weight, silk is stronger than steel, but not as strong as Kevlar. Silk is,however, tougher than both.This paper inform about overview on the today trend in the world of spider silk

A STEP TO A PERFECT GARMENTS FACTORY [REVIEW]

In this paper was exposed the tendences of the most important designers and producers of integrated transportation sistems. The transportation system is one of the most important problem in the garments fabrication economy. Beginning from unprocessed goods,cutting area,process management,finishing area,quality check to the warehouse, distribution and dispatch zone the basic idea was the same: unlimited railing from centrally-suspended rail servicing all kinds of work stations with application specific trolleys. Ergonomic work station design, linking work stations and areas, manual, semi-automatic and automatic, modular set ups lead to intralogistic systems for the entire factory.The articles are transported from a post to another post by a suspended trolley. The system for apparel industries is a flexible material handling system designed to eliminate manual transportation and minimize handling. It increases productivity radically, ensures an optimal working flow and provides time for adding value to your products. Technically the system consists of overhead conveyors with individually addressable product carriers, automatically finding its way to the correct operation. It is monitored by a computer providing all necessary data for measuring and managing the process optimally. Furthermore, the system is highly flexible and can rapidly be modified to changes in the production line or the need for expansion.In the same time introduce foreign technology, research and develop independently from hardware to software,. customize the special need of the customers and upgrade and expand the function easily

ULTRASONIC ASSEMBLY [REVIEW]

The paper exposes the possibility of machine producesers to optimize the costs of clothes assembling. Ultrasonic systems being frequently utilized have many advantages on semi products of synthetic textile and technical textile. First of all, sewing – cutting process can be accomplished under high speeds and rate of losses can be minimized. Cutting seal applications are frequently used for underwear and sportswear. Slicing and unit cutting machines, as well as portable sealing machines are available for labeling sector. Products such as bag, pocket and cover can be sewed in a seamless manner for promotion purposes. All objects in terms of accessories are obtained in same standard. Our quilting machines are preferred in worldwide due to its threadless, high quality sealing. An alternative to the classic sewing assembly, with thread and needles is ultrasonic seaming. In ultrasonic welding, there are no connective bolts, nails, soldering materials, or adhesives necessary to bind the materials together. Ultrasonic is defined as acoustic frequencies above the range audible to the human ear. Ultrasonic frequencies are administered to the fabric from the sonotrode of bonding machine. The high frequency and powerful energy produced, when is release in one special environment, the ultrasound heating this environment. The ability to ultrasonic weld textiles and films depend on their thermoplastic contents and the desired end results. The paper defines the weld ability of more common textiles and films. The welding refers to all types of bonding and sealing, as in point bonding of fabric, or continuous sealing of film

THE INFLUENCE OF DOUBLING OF TEXTILE MATERIALS THROUGH THERMOFUSING ON THEIR HIDROPHILICITY

In the textile industry, the majority of clothing products, especially outerwear products, have some parts doubled up through thermofusing with other textile fabrics, woven or nonwoven, in order to provide some volume of shape, to fix contours, or to confer dimensional stability to the respective area . In this paper, we aim to highlight the influence on hydrofilicity of natural fiber materials of vegetable origin - flax and cotton - and of mixed natural fiber materials, by the process of doubling through thermofusing with chemicalized materials, woven or nonwoven. From laboratory measurements of the moisture absorption ability for these materials, fused or nonfused, woven or nonwoven, we conclude on the influence of these processes on the hydrofilicity of the fused ensemble and over the sanogenetic indicators that any fashion product must ensure for the wearer. Ensuring the comfort and compliance of clothing products is a priority of the producers of fabrics and textile garments. A clothing item should ensure optimum insulation, breathability, moisture absorption and air permeability to give the wearer comfort, wellbeing and safety. We focused on natural fiber materials of plant origin, since they are increasingly being used in the textile industry with beneficial influences on the state of comfort of the wearer
